Frequently Asked Questions (FAQ)
Q1: What defines the 'graphitization ratio' in Graphitized Petroleum Coke/Low Nitrogen Recarburiser?
A: It is the percentage of carbon atoms converted to crystalline graphite structure under high-temperature (up to 3000°C). High ratio (>95%) ensures rapid dissolution and minimizes inclusion defects in metallurgical melts.
Q2: How does nitrogen content affect steel or ductile iron production?
A: Lower nitrogen (<300ppm) prevents pinhole formation, reduces gas porosity, and enhances impact toughness and ductility per ISO/TR 25901-2:2019.
Q3: Are there international certifications applicable to this recarburiser?
A: Yes. Common certifications: ISO 9001/14001 (system, environmental), ANSI/EN standards (chemical composition), REACH (EU chemical compliance).
Q4: What determines the service life of carbon linings or castings made with this product?
A: Largely the sulfur/nitrogen content and ash level; lower contaminants mean less oxidation/corrosion and enhanced lifecycle (often exceeding 5 years in lining use cases).
Q5: Does particle size calibration matter for foundry application?
A: Yes. Graphitized Petroleum Coke/Low Nitrogen Recarburiser can be calibrated to 0.2–30mm, optimizing surface area/dissolution rate for high-throughput metal melts.
Q6: What are typical installation or incorporation standards?
A: Compliance with ISO 12985 (carbon materials), proper blending during charge or later as 'add-back' in melt, and ensuring even mixing as per ASTM E1019 (batch traceability).
Q7: How do you ensure the product is free of residual metallics and hazardous impurities?
A: Multi-step calcination, advanced graphitization (CNC control), and post-process ISO/SGS-certified third-party testing guarantee non-detectable levels of metallics and dangerous volatiles.
